Scientific study shows that pop song lyrics are getting sillier. What are the lyrics of a song? Is it literature as Bob Dylan's Nobel Prize ruling said? Or is it the way a musical instrument expresses itself called the human voice? The study has considered 352,320 songs written or sung in English and published in 1970 and 2020, between the year of Bridge over troubled water by Simon and Garfunkel and that of Blinding Lights by The Weeknd.
It found that letters have become simpler over time in many ways: vocabulary richness, legibility, complexity and repeated lines.
